A million little bugs - hashcat dev

The SP1 Rollup 4 does its job on updating better then the Rollup 3 but still not 100% correct. If you have customized your logon.aspx it will overwrite your files but with some little errors who leads to a missbehavior. The page will indeed show up but does not proceed the logon and will redirect you back to the logon each time you try to login.
To solve this you will have to do the same as at the Rollup 3 update, put your original logon.aspx from Rollup 3 back in and let the Rollup 4 do its job. Then you can apply your patches again.
Same procedure as every rollup..
